Gothenburg Botanical Garden

Improved Quality and Propagation in High Altitude Plants

Application: Greenhouse

Crop type: Alpines, Dionysia

Gothenburg Botanical Garden, with 175 hectares is one of the largest botanical gardens in Europe. The cultivated areas occupy 40 hectares. The garden and greenhouses currently house about 16 000 species of plants. Of these, a large number is their scientific collections, including one of Europe’s biggest collections of bulbs, tuber plants, alpines, and Dionysia.

The Heliospectra solution gave us the best result ever. Now with the LX60, we receive even better results. We experience benefits such as increased quality, more balanced foliage and sturdy flowers. We have also received great results on our cuttings. What’s really impressive is that 100% of our Dionysia cuttings survive. That is exceptional!

SITUATION
Onions, tuber plants, alpines, and Dionysia are some of the Garden's most demanding plants. They are heat sensitive plants in need of quality lighting, explains Marika Irvine, gardener at the Gothenburg Botanical Garden.

The traditional HPS lighting the Botanical Garden used did not emit enough light. The extra heat the HPS lamps generated was affecting the quality of the plants, leading to spindly leaves and flowers, says Marika Irvine.

SOLUTION
To avoid unnecessary heat generation and improve light levels the Botanical Garden chose to invest in LED lighting.

They started using Heliospectra L4A in 2013 and got very good results. Since the fall of 2014, they use the new energy-efficient and fully controllable Heliospectra LX602.

"A positive surprise is that they usually have problems with aphids, even in winter, but last year almost no aphid infestation was noted. Aphids do not like blue LED light - a fantastic bonus, isn’t it?" says Marika.
